The First Minute of an Emergency Decides More Than You Think
Most of what goes right or wrong at an emergency happens before anyone touches the patient. What the first minute asks of you, and what this week covers.
Jarrett Chisholm, ACP · October 5, 2026
Ask paramedics what separates the calls that go well from the ones that do not, and most of them will not start with anything they did. They will start with what happened before they arrived. Somebody noticed. Somebody called early and gave a clear address. Somebody started compressions, pressed on the bleeding, or rolled a person onto their side. By the time an ambulance pulls up, the most important decisions of the whole emergency have usually been made by whoever happened to be standing there.

Hockey rink or community centre lobby. An adult lies on the floor; a bystander kneels at his shoulder, head turned, arm out, pointing directly at one person in a small group who is lifting a phone to their ear. Others in the background are still standing. Ordinary winter clothing, no blood, faces calm rather than panicked.
Alt text ready: “In a hockey rink lobby, a bystander kneels beside a collapsed man and points at another person who is already dialling a phone.”
That first minute is also the hardest one to get right. It arrives without warning, usually in an ordinary place: a kitchen, a hockey rink lobby, a job site trailer, a grocery store aisle. Nobody is in uniform and nobody is in charge. The people present are trying to work out whether what they are seeing is real, whether it is serious, and whether it is their job to do something about it.
This week is about that minute. Not the advanced care that comes later, but the handful of things that decide whether later goes well: noticing, deciding, calling, and starting. None of it needs equipment. All of it can be learned, and most of it is less about knowledge than about having a plan before you need one.
Time matters more here than almost anywhere else in first aid. When the heart stops, every minute without CPR or a defibrillator costs a large share of the person's chance of survival. A minute spent wondering whether to act is not a neutral minute.
Freezing is normal, and it is fixable
Almost everyone who has walked into a real emergency describes a moment of not moving. The brain is trying to match what it sees to something familiar and it cannot. Some people describe it as the scene going quiet, or time slowing down. This is not cowardice and it is not a character flaw. It is how people are built. what a frightening call can leave behind afterwards.
The fix is not courage. It is a script. People who have practised a short sequence of steps under a bit of pressure move sooner, because the first step is already decided for them. That is the whole reason first aid courses drill the same opening over and over: check the scene, check the person, call, care. The words stop being a lesson and become the thing your body does while your brain catches up.
If you have never been trained, you can still borrow the script. Say out loud what you see. Tell someone to call 911. Get down beside the person and ask them if they are okay. Speaking and moving breaks the freeze faster than thinking does.
Everyone assumes somebody else has called
The more people standing around an emergency, the less likely any one of them is to act. Each person sees the others and assumes that someone more qualified, or closer, or more confident, is already handling it. A crowd of twenty can watch a person struggle for a surprisingly long time with nobody having dialled a phone.
The way through is to be specific. Pick one person, look at them, and give them one job: you in the blue jacket, call 911 and tell me when they answer. Pick another person and send them for a defibrillator or a first aid kit. Specific requests get done. General ones, like somebody call an ambulance, often do not. rehearse a 911 call before you ever have to make one.
If you are the one being pointed at, do the job and report back. Say out loud that you have called. That single sentence stops three other people from wondering whether they should.
The few things that cannot wait
Most injuries and illnesses give you time. A sprained ankle, a small cut, a person who feels faint and sits down: these are real, but a few minutes spent getting organised changes nothing. A short list of problems is different. They kill quickly, and what a bystander does in the first minute is often what decides the outcome.
The emergencies where the first minute matters most:
- A person who is unresponsive and not breathing normally. Call 911, start chest compressions, and send someone for a defibrillator.
- Bleeding that is spurting, pooling, or soaking through clothing. Press hard on it with whatever you have and do not let go.
- Someone choking who cannot speak, cough or breathe. Start back blows and abdominal thrusts right away.
- A person who is unresponsive but breathing. Keep the airway open, often by rolling them onto their side, and call 911.

Four equal panels in Delta gold and charcoal, each with a plain line icon and a two-word label: chest with no breath lines for not breathing, a hand pressing on a forearm for severe bleeding, a hand at the throat for choking, and a person on their side for unresponsive but breathing. Under each, the first action in four or five words. No gore.
Alt text ready: “A simple four-panel diagram showing the emergencies that need action in the first minute: not breathing, severe bleeding, choking, and unresponsive but breathing.”
Almost everything else can wait for a calmer look, a proper assessment, and help to arrive. These four cannot. Knowing the difference is most of what lets you stay calm about the rest. a short course built entirely around severe bleeding.
What the rest of this week covers
On Wednesday, a piece held over from last week's heart series looks at why a heart attack so often goes unrecognised, including by the person having it. It belongs here too: the first minute of a heart attack is the minute someone decides whether to call.
Thursday's clinical post takes on the single most important judgement in the first minute: is this person breathing normally? It is harder than it sounds, because a person whose heart has stopped often keeps making gasping breaths for a while, and those gasps fool people into waiting.
Saturday is the three words at the centre of Canadian first aid training, Check, Call, Care, and what each one actually asks of you in order.
None of these posts replace practice with your hands. They are here so that the first minute has a shape before you ever find yourself in one.
Quick answers
- What is the first thing to do in an emergency?
- Look before you step in. Check that whatever hurt the person is not about to hurt you too, then check the person: are they responsive, and are they breathing normally? That takes seconds and decides everything that follows, including what you tell 911.
- Why do people freeze in an emergency?
- Because the brain is trying to match an unfamiliar scene to something it knows. It is normal and happens to trained people too. The difference practice makes is that the first step is already decided, so you start moving sooner. Speaking out loud and giving someone a job both help break the freeze.
- Should I call 911 before I start helping?
- If the situation looks serious, get the call started as early as you can. If other people are there, send one specific person to do it while you begin. If you are alone with an adult who is unresponsive, put the phone on speaker and call first, so the dispatcher can coach you while you work.
